Expression syntax

[Paul Benedict]

Neal/Remi, perhaps you could give your opinion on this one. To me,
having well-formatted code to make easy readability is important to
me. It's very important. I don't find it very readable without the use
of braces to enclose the lambda function.

Example:
#int(String) fun = #(String text) text.length();

If braces aren't mandatory, are they validly optional? I would rather write:
#int(String) fun = #(String text) { text.length(); }

And that could allow my IDE formatters to run their rules based on how
to handle braces. If someone likes breaking, this can remain possible:
#int(String) fun = #(String text) {
   text.length();
}

If someone likes to inline everything, this could be possible too:
object.call(a, b, c, #(String text) { text.length(); });

Just to be clear, my focus here is on flexibility to take advantage of
existing IDE formatting options surrounding braces.
